DETAILED DESCRIPTION

[0042] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] The utility model relates to a mixer for oral restoration materials. Figures 1 to 5 Shown, including:

[0044] The support mechanism 1 is independently fixed and can be made of high-strength stainless steel to ensure the stability of the entire device during operation;

[0045] The mixing barrel 2 can be made of medical-grade stainless steel with high corrosion resistance. Its capacity can be customized according to actual needs. The mixing barrel 2 is firmly mounted on the supporting mechanism 1 by fasteners. A circular notch is provided on the top of the mixing barrel 2. The notch is equipped with a sealing cover 3 to ensure that the material will not leak during the mixing process.

[0046] The mounting member 4 is rotatably arranged in the inner hole of the sealing cover 3 and realizes relative rotation with the sealing cover 3 through a bearing, and the rotation axis of the mounting member 4 is coaxially arranged with the inner cavity of the mixing barrel 2, ensuring uniform distribution of the material during the mixing process;

[0047] Two stirring shafts 5 are rotatably mounted on the mounting member 4, and a plurality of stirring paddles 6 are equidistantly arranged on the stirring shaft 5. The design of these stirring paddles 6 takes into account the principles of fluid dynamics and can effectively promote the flow of materials to ensure uniform mixing;

[0048] The transmission mechanism 7 is provided on the mounting member 4 and is used for synchronous rotation of the two stirring shafts 5, thereby ensuring the consistency of the mixing process;

[0049] The driving mechanism 8 is provided on the sealing cover 3, and the driving mechanism 8 drives the mounting member 4 and the transmission mechanism 7 to rotate, providing the necessary torque to drive the entire stirring system;

[0050] The cleaning mechanism 9 is provided on the mounting member 4 and is slidably mounted on the inner wall of the mixing barrel 2. When the mounting member 4 rotates, the cleaning mechanism 9 can scrape off the material adhering to the inner wall.

[0051] When the device is working, the stirring shaft 5 has two working modes at the same time, including rotation mode and revolution mode. When the repair material is mixed, the driving mechanism 8 is started, and the stirring state is entered. The stirring shaft 5 simultaneously revolves and rotates. The specific working process and principles of the two modes are as follows:

[0052] In the rotation mode, the driving mechanism 8 drives the two stirring shafts 5 to start synchronous rotation through the transmission mechanism 7. The stirring paddles 6 arranged at equal distances on the stirring shafts 5 are designed according to the principles of fluid dynamics. They can generate effective shear force and turbulence during rotation, thereby promoting full mixing of the materials. At the same time, the two stirring shafts 5 provide two different directions of rotational force to the repair material in the mixing barrel 2, further improving the mixing efficiency.

[0053] In the revolution mode, the driving mechanism 8 drives the mounting part 4 to rotate synchronously, thereby driving the stirring shaft 5 to revolve around the rotation axis of the mounting part 4. This design allows the stirring position to be continuously changed, thereby improving the stirring efficiency of the repair material. While stirring, the cleaning mechanism 9 installed on the mounting part 4 will also rotate accordingly. The cleaning mechanism 9 maintains sliding contact with the inner cavity wall of the mixing barrel 2, and can continuously remove materials adhering to the barrel wall during the stirring process to prevent material residues from affecting the subsequent mixing effect or causing equipment pollution.

[0054] like Figures 3 to 5 As shown, as a preferred solution, the transmission mechanism 7 includes:

[0055] The mounting shaft 71 is provided on the mounting member 4. The design of the mounting shaft 71 needs to take into account sufficient strength and rigidity to withstand the torque from the driving mechanism 8, and the mounting shaft 71 is located outside the mixing barrel 2;

[0056] The hollow shaft 72 is a hollow shaft that is rotatably mounted on the mounting shaft 71 , and the mounting shaft 71 and the hollow shaft 72 are coaxially disposed, allowing the hollow shaft 72 to rotate freely relative to the mounting shaft 71 ;

[0057] The driving gear 73 is coaxially arranged on the hollow shaft 72, and the hollow shaft 72 provides a stable rotation center for the driving gear 73;

[0058] Two driven gears 74 are coaxially arranged on the two stirring shafts 5, and the driving gear 73 is meshed with the two driven gears 74. The design of the driven gear 74 must ensure correct meshing with the driving gear 73 to ensure effective power transmission;

[0059] The working principle of the transmission mechanism 7 of this device is as follows:

[0060] When the driving mechanism 8 is started, the power is first transmitted to the hollow shaft 72 through the mounting shaft 71. The rotation of the hollow shaft 72 drives the rotation of the driving gear 73. The driving gear 73 transmits the rotational power to the two stirring shafts 5 by meshing with the two driven gears 74, so that the two stirring shafts 5 can rotate synchronously.

[0061] like Figures 2 to 4 As shown, as a preferred solution, the driving mechanism 8 includes:

[0062] The drive motor 81 is mounted on the sealing cover 3. The drive motor 81 must be fixed to ensure that it is stable and reliable during operation without vibration or loosening. The rotation axis of the drive motor 81 coincides with the rotation axis of the mounting member 4. The selection of the drive motor 81 should take into account its power and speed to meet the power requirements of the stirring system.

[0063] The first bevel gear 82 is coaxially fixed to the output end of the driving motor 81;

[0064] The second bevel gear 83 is coaxially disposed on the mounting shaft 71 and is meshed with the first bevel gear 82. The design of the first bevel gear 82 must ensure correct meshing with the second bevel gear 83 to achieve effective power transmission;

[0065] The third bevel gear 84 is coaxially arranged at the output end of the driving motor 81;

[0066] The fourth bevel gear 85 is coaxially arranged on the hollow shaft 72 and meshed with the third bevel gear 84. The design of the third bevel gear 84 must ensure correct meshing with the fourth bevel gear 85 to achieve secondary power transmission. The materials of the first bevel gear 82, the second bevel gear 83, the third bevel gear 84 and the fourth bevel gear 85 should have sufficient strength and wear resistance to withstand long-term operation.

[0067] The working principle of the driving mechanism 8 of this device is as follows:

[0068] When the driving motor 81 is started, the first bevel gear 82 at its output end begins to rotate. The first bevel gear 82 transmits the rotational power to the mounting shaft 71 through meshing with the second bevel gear 83. The rotation of the mounting shaft 71 drives the rotation of the mounting member 4, thereby causing the stirring shaft 5 to revolve around the axis of the mounting member 4.

[0069] At the same time, the third bevel gear 84 at the output end of the drive motor 81 also starts to rotate. The third bevel gear 84 transmits the rotational power to the hollow shaft 72 through engagement with the fourth bevel gear 85, and then the rotational power is transmitted to the two stirring shafts 5, so that the two stirring shafts 5 can rotate synchronously.

[0070] like Figure 1 As shown, as a preferred embodiment, a protective cover 10 is provided on the sealing cover 3. The protective cover 10 can be made of high-strength, corrosion-resistant stainless steel or engineering plastic to ensure its durability and safety in long-term use. The first bevel gear 82, the second bevel gear 83, the third bevel gear 84 and the fourth bevel gear 85 are all located inside the protective cover 10 to prevent the operator from accidentally contacting the high-speed rotating gear components during the operation of the equipment, thereby ensuring safe operation.

[0071] like Figures 3 to 5As shown, as a preferred embodiment, the cleaning mechanism 9 includes:

[0072] The fixing member 91 is provided on the mounting member 4. The fixing member 91 can be made of high-strength, corrosion-resistant stainless steel or engineering plastic to ensure its durability and safety in long-term use. The fixing member 91 is slidably connected to the sealing cover 3 to promptly clean the repair material splashed onto the sealing cover 3 during stirring.

[0073] Two scrapers 92 are provided on the fixing member 91. The scrapers 92 can be made of flexible or semi-rigid materials, such as food-grade silicone, polyurethane or Teflon, to ensure that when they come into contact with the inner wall of the mixing barrel 2, they can effectively scrape the material without damaging the inner wall. The two scrapers 92 are symmetrically arranged with respect to the rotation axis of the mounting member 4 to ensure that they are in stable contact with the wall of the mixing barrel 2 when rotating with the mounting member 4.

[0074] The bottom plate 93 is provided on the two scrapers 92. The bottom plate 93 can be made of the same material as the scrapers 92. The bottom plate 93 is slidably connected to the bottom wall of the mixing barrel 2, which can effectively scrape off the material without damaging the bottom wall.

[0075] The working principle of the cleaning mechanism 9 of this device is as follows:

[0076] When the driving mechanism 8 is started, the mounting member 4 starts to rotate under the drive of the driving motor 81;

[0077] The fixing member 91 rotates together with the mounting member 4. Since the fixing member 91 is connected to the sealing cover 3 by sliding, it is ensured that it can slide smoothly during the rotation process, and the mixed material splashed on the top wall is cleaned in time;

[0078] The two scrapers 92 rotate together with the fixing member 91, maintaining a slight contact pressure with the inner wall of the mixing barrel 2. During the rotation process, the scrapers 92 continuously scrape off the material adhering to the inner wall of the mixing barrel 2 to prevent material residue;

[0079] The bottom plate 93 rotates together with the scraper 92, maintaining a slight contact pressure with the bottom wall of the mixing barrel 2. During the rotation process, the bottom plate 93 continuously scrapes off the material adhering to the bottom wall of the mixing barrel 2 to ensure stable mixing of the repair material.

[0080] like Figure 4 As shown, as a preferred embodiment, two positioning columns 94 are provided on the bottom plate 93. The positioning columns 94 can be made of high-strength, corrosion-resistant stainless steel or engineering plastic to ensure its durability and safety in long-term use. The two positioning columns 94 are respectively arranged coaxially with the two stirring shafts 5 to further position the stirring shaft 5 during rotation, improve the rotation stability of the stirring shaft 5, and prevent the shaking from affecting the service life of the device.

[0081] like Figures 1 to 2 As shown, as a preferred solution, the support mechanism 1 includes:

[0082] The support member 11 is provided on the outer wall of the mixing barrel 2. The support member 11 can be made of high-strength, corrosion-resistant stainless steel material to ensure its durability and safety in long-term use;

[0083] The support leg group 12 is arranged on the support member 11. The support leg group 12 can be made of high-strength, corrosion-resistant stainless steel or engineering plastic to ensure its durability and safety in long-term use, and the support leg group 12 includes at least three support legs set at equal angles. The design of each support leg should ensure that it can stably support the entire device. The length and diameter of the support leg should be matched according to the weight and size of the mixing barrel 2 to ensure its stability during operation. The three or more support legs of the support leg group 12 are set at equal angles to ensure the balance of the center of gravity of the entire device to prevent tipping or shaking during operation.

[0084] like Figure 3 As shown, as a preferred embodiment, the bottom end of the mixing barrel 2 is set to a spherical surface. The design of the spherical surface helps to reduce the residue of material at the bottom, ensuring that the material can be discharged smoothly, and a valve is provided at the lowest point of the spherical surface to ensure that the material can be completely discharged without leaving any residue.

[0085] The installation, connection or setting method of the oral restoration material mixer of the present invention are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
